Abstract : The report summarizes the research completed under this contract. The work has been reported in 19 journal or proceedings articles, and in 7 published reports. Areas studied include transport coefficients in partially ionized two-temperature plasmas, the effects of nonelastic collisions on the kinetic-theory of high temperature gases, ionization rates including nonelastic collision effects, the nonequilibrium boundary layer in flowing plasmas, vibrational interactions in rapidly expanding gases, stability and breakdown phenomena in plasmas flowing through magnetic fields, current distributions and discharge characteristics, and diagnostic techniques. The work is summarized under four broad categories : MHD Generator-Related Experiments, Properties of Nonequilibrium Collision Dominated Plasmas, Diagnostics, and Nonequilibrium Measurements in Rapidly Expanded Flows.
